Magnetic Corner Clip for Damage-Free Document Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clipboards are inconvenient for viewing multi-page documents, as they often damage the paper with clips or staples and require complex removal mechanisms, limiting flexibility in document orientation.
Innovation Solution
A clipboard with a magnetic clip portion extending from the top corner of a plate body, featuring multiple folding fixing members with magnetic portions to securely hold documents without leaving marks, allowing for easy orientation changes and convenient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clip or stapler is used to fix the document paper, then the document paper is securely fixed, but marks are left on the document paper or the paper is damaged
Solution Approach 1:
The patent replaces the mechanical clip or stapler fixing system with a magnetic fixing system. The magnetic portion generates magnetic force to attract and fix the document paper without physical contact or penetration, thereby eliminating paper damage and marks while maintaining secure fixation.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the clipboard and the document paper. Instead of direct mechanical contact, the magnetic field acts as a mediator to hold the paper in place, avoiding harmful physical interaction with the paper surface.
2Ease of operation
If the fixing mechanism is designed to be easily removable, then document disposal is convenient, but the fixing mechanism may not securely hold the document paper
Solution Approach 1:
The patent employs a foldable magnetic fixing mechanism that can dynamically change between an extended fixing state and a retracted storage state. When extended, the magnetic portion securely holds the document; when folded back, it releases the document for easy removal, allowing the same mechanism to provide both secure fixation and convenient removal.
Solution Approach 2:
The fixing mechanism is divided into separable components: the magnetic portion that contacts the document and the support structure. This segmentation allows the magnetic portion to be independently positioned for secure fixing while the overall mechanism can be folded or adjusted for easy document removal and disposal.
3Reliability
If the clipboard is designed to fix the entire top or side of the document paper, then the document is securely held, but it is inconvenient to view the document in different orientations
Solution Approach 1:
The patent applies magnetic fixing at a localized corner position rather than along the entire edge of the document. This localized fixing point provides sufficient security to hold the document while allowing the rest of the document to remain free and flexible for various viewing orientations and positions.
Solution Approach 2:
The foldable design of the magnetic fixing mechanism allows it to adapt to different document orientations. The mechanism can be positioned at different corners or adjusted in its folded state to accommodate landscape, portrait, or angled viewing positions while maintaining secure fixation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The clipboard provides secure document fixation without damaging the paper, offers flexibility in document orientation, and reduces manufacturing costs through injection molding or extrusion molding with a steel material.

AI summary
A clipboard includes a plate body formed to have a predetermined area to support document paper; and a clip portion extending from one corner of the plate body and fixing the document paper seated on the plate body to prevent the document paper from being separated from the plate body. The clip portion includes a second fixing member, a first fixing member extending from the second fixing member, and a third fixing member formed symmetrically with respect to a boundary surface between the second fixing member and the plate body; the second fixing member is configured to be folded with between the second fixing member and the plate body to cover the document paper; and the first fixing member is configured to be folded with respect to a boundary surface between the first fixing member and the second fixing member, so that the document paper can be fixed.
